Does anyone know about C++ codes about this subject?

In Chapter 4 we talked a bit about the sizeof operator (section 4.8). Write code that will output the size of the various data types o char o short int o int o long int o float o double float o boolean The output should put each size on a different line: The size of a char is: The size of a ..... 1 bytes One line for each of the types. Sizeof What?? Every data item, constants and variables, not only have a data type, but the data type determines how many bytes the item will use in the memory of the computer. The size of each data type varies with the compiler being used and the computer. This effect is known as being machine dependent. Additionally, there have been some size changes with upgrades to the language. In "C" the int data type was allocated 2 bytes of memory storage on an Intel compatible central processing unit (cpu) machine. In "C++" an int is allocated 4 bytes. There is an operator named "sizeof (...)" that is a unary operator, that is it has only one operand. The operand is to the right of the operator and is placed within the parentheses if it is a data type. The operand may be any data type (including those created by typedef). If the operand is an identifier name it does not need to go inside a set of parentheses. It works for both variable and memory constant identifier names. This operator is unique in that it performs its calculation at compile time for global scoped items and at run time for local scoped items. Examples: cout
